Cost optimization of fiber deployment for small cell backhaul

Abstract: We discuss an optimization framework for planning a cost-minimized GPON backhaul deployment for small-cell networks. Compared to typical Ethernet based point-to-point fiber backhauling approaches, this technique can save half of the deployment costs.

Passive ROADM Flexibility in Optical Access With Spectral and Spatial Reconfigurability

Abstract: An energy-aware solution for physical-layer reconfigurability in metro-access networks is presented. The dynamicity of optical switching is introduced in nodes that are perceived as fully-passive by the network. Energy scavenging at low optical feed level of $- 10\;{\text{dBm}}$ supports field-deployment without local electrical power supply. Two types of network nodes are demonstrated experimentally. First, a resilience node is evaluated for fast protection switching in 10.7 ms at the feeder segment. Optical switching is further exploited for the purpose of dynamic allocation of spectral slices and routing in a new class of reconfigurable optical add-drop multiplexer. The spectral bandwidth of drop segments can be extended on demand while intranetwork communication among different segments of the access network is also enabled. Finally, we discuss the potential for realizing self-powering by means of tapping optical signals traversing the access network rather than utilizing a dedicated pump source.

Adaptive scheduling for differentiated services in an Ethernet passive optical network

Abstract: Feature Issue on Optical Access Networks (OAN) The Ethernet passive optical network (EPON) is a technology viewed as an attractive solution to the "last mile" problem. The interleaved polling with adaptive cycle time (IPACT) is a remarkable medium access control (MAC) protocol for EPONs. The IPACT scheme supports two stages of scheduling. One is inter-optical network unit (ONU) scheduling. The other is intra-ONU scheduling. In this paper, we propose a systematic adaptive scheduling scheme to enhance the functions of the IPACT on both types of scheduling in order to achieve efficient bandwidth utilization of EPONs under unbalanced traffic and to provide class-of-service (COS) or differentiated services within an ONU. The simulation results show that our proposed scheduling scheme can improve the performance of the EPON system under unbalanced traffic loads and provide fair bandwidth allocation of the uplink to different types of traffic.

Performance benefits of optical circuit switches for large-scale dragonfly networks

Abstract: We propose Optical Circuit Switching for dynamically creating reconfigurable partitions in large-scale systems with Dragonfly networks. Up to 2x execution-time improvement is demonstrated for global traffic patterns in a >13,000-node system using a production-grade network simulator.

Optical grooming in OFDM-based elastic optical networks

Abstract: We propose a novel optical grooming approach to aggregate and distribute traffic directly at the optical level in OFDM-based elastic optical networks. Significant transmitter and spectrum saving is achieved compared to non-grooming scenario.
